There are millions of animals living on our planet Earth.
But every animal cannot exist in every habitat because of different environmental factors
For example, in polar regions, you cannot find animals such as snakes.
The body of the organism should be adapted to the conditions in the place to be able to survive there.
Here, let's see how some animals can survive in the extreme cold conditions of polar regions.
Let us see the polar adaptations in animals
Polar regions include the Arctic and Antarctic regions of our planet. It includes countries like Canada, Sweden, Greenland etc.
The polar regions are covered with snow for most parts of the year. Sometimes the temperature could go as low as -37o C.
Polar bears are one type of animals exclusively found in the polar regions.
Let us learn about the adaptations of polar bears.
They have white fur, which makes them less visible in the snowy background and helps them escape the predators and also to catch prey.
They often have 2 thick layers of fur and a fat layer under their skin, which insulates and keeps them warm from the nail-biting cold.
They have wide and large paws with long, curved and sharp claws which help them in swimming and walking on the snow.
While they’re swimming under water, they can close their nostrils and stay underwater for a long time.
They have an incredible sense of smell and it helps them capture their food.
Another common animal in polar regions is Penguin
The majority of it’s body is also white in colour, which helps in merging with the background.
Similar to polar bears, it also has a thick skin and fat layer to protect it from the cold.
The penguins are seen huddled together. They do this to keep themselves warm.
Penguins are good swimmers. They have a streamlined body and webbed feet, which help them in swimming.
Let us see the adaptations of some other animals found in the polar areas.
Many types of fishes, whales, foxes, birds, reindeers, seals etc. are found in the polar regions.
The fish have the ability to remain underwater for a long time. Arctic Cods, snailfishes, sharks, rays etc. are few fishes found in oceans in polar regions.
Birds needs warmer conditions for survival and hence they migrate to warmer habitats when winter kicks in.
Siberian crane is such a migratory bird, who migrates from colder areas such as Siberia to Rajasthan (Bharatpur) and Haryana (Sultanpur).
When the winter season is over, these birds travel back to their original countries.
Fun fact: Some birds travel over 15000 km to escape the extreme conditions at their home.
Also it is still a mystery how they travel to the same place year after year. It is believed they have some inbuilt mechanism for sense of direction.
It is believed that these migratory birds use navigation with the help of stars, landmark or even the magnetism of the earth.
Polar regions are extreme cold regions of the Earth.
Polar bears have adaptations such as thick fur and skin with fat layer to protect them from cold. They also have white fur to escape the predators and great sense of smell which helps them hunt their prey.
They have large paws and long curved claws which help them in swimming as well as walking in the snow.
Penguins have mostly white bodies, which help them in merging with the background. They also have thick skin and a fat layer which protects them from extreme cold.
They have webbed feet and streamlined bodies which help them in swimming with ease.
Some types of fish are adapted to survive in the cold water. Birds migrate to warmer habitats during winter and come back after the winter.
